Both turbochargers are going to make high power on pump and race gas. What are your goals with this setup?

There hasn't been much testing that I know of with the 6466 but it does look promising. I would wait a couple of weeks to see what is released from PTE as far as who tested it and there results.

yah that why I'm still waiting , but I think the 6766 is the best for really high power .

Both turbos maxed out the 6766 will make more. The 6466 will be close but will not make the peak number the 6766 will but will have a better power curve

Both turbo's are rated for the same horsepower. I have seen 50psi on both turbo's make 950whp.

Wow. What is the most you have seen out of a 6266. I cant believe 6266 to 6466 people are seeing 200HP. I would think more like 100whp for the change but I have yet to see a 850whp 6266 graph.

Nobody said there was a 850whp 6266 graph?

PTE says a 6266 was 735 and the 6466 is 900.

maybe i am confused. you said the 6266 and 6466 are rated the same. or did you mean the 6766/6466

You misnterpreted what I was getting at. Sorry I should have been more clear.

If the 6466 has made a witnessed 950whp on a dynojet I would think the difference between the 6266 and 6466 would only be 100hp at best for the mechanical difference bewteen the two turbos.

I have yet to see a 850whp 6266 graph. Have you? If there is a 6466 graph at 950whp dyno jet it makes me optimistic that a 6266 could crank out 850whp dynojet on kill in a well equipped set up.
